I'm old. So here's what I've heard/been told - rotating foods removes the go-tos if they develop a sensitivity to a source - whether protein or grain. - rotating can mess with their gut & lead to bloat (my experience validates the last). Feeding dogs has gone the way of training dogs -- as the only thing two trainers agree on is that the third trainer is doing it wrong.

Talk to your vet about gas. Look at what's in the feed that gives him gas vs the feeds that = loose stools -- That might provide an insight as to what to avoid in a food. BTW I was excited when I moved to Arkansas because there were all these options of high quality kibble to feed. And the fancy feed = pudding output. So I quit feeding that.

Thank you for the info. Your explanation sounds very true. These people that rotate think its better, but I see now that it is not better. Pardon me in my last post I wasn't calling you old, I was just explaining how the old school is better. That's just a saying my mom always uses. At the time I was believing everyone else with rotating and I am sorry I listened. You have a very good point with the gas, using different foods disturbs the flora in the gut and then you get gas. If this pro plan works I am not changing it, if not I will ask the vet and if we find something good I will stick with it. Again thank you.

Middle, I forgot to mention, since we are talking about gas can be from changing foods; could it be that the gas is not from the pro plan, and he just needs to adjust to it? He's only been eating it for 2 months. Just a thought.

I'd think a week would be an adequate time for adjustment. Two months, plenty of time.

I am old. You didn't call me old. I just acknowledged it.

I don't know the science behind rotating/not rotating food. But given you have had a hard time finding one that works, I would hesitate to rotate. I think some people on this board had the name of a nutritionist that they used and liked. Maybe they will weigh in.

Hi Middle, I just bought nature's Variety can LID lamb last night, I gave him that with only a little pro plan dry. Today his stool was solid from the can food. His stool is soft on purina pro plan and light. So should I just give him the can food since it is agreeing with him? I don't think the dry pro plan is for him. I want to use dry food, but I am afraid to try any right now.

My concern remains with your never ending switch of food. I understand you are trying to find the best but it seems like nothing feels right to you. Maybe you are right. I wouldn't worry about whether the food was wet, dry, canned, fresh so long as he does well on it.I cannot tell you what you "should" do and if I did you wouldn't do it. I'm going to guess that in a bit you are going to get fussy about the canned for some reason and switch again.

Middle, you know me quite well, It does seem I am too picky with food. I guess since I had a bad experience with my other GSD. Years ago when I had Max I never switched his food. He ate one type of dry all of his life, until one day the company changed formulas and I was not to smart then about food. Well anyway he got really sick, so I went to the store and bought another brand, he loved it good stool and that was that, until it got recalled and here I go again and then finally my 13 year old dog got skinny from not eating and I cooked for him. So I was NEVER picky before and now I can't help that I know to much. Not sure if knowing to much can hurt me.

Hi Middle, I enjoy talking to you, and sorry if sometimes I don't take advice. However I am trying b/c I know people like yourself and others are really trying to be helpful and also you and everyone here are very knowledgeable. I am glad I joined this forum. By the way do you have any snow where you live right now? I do and I am not that happy. I used to love snow.

I bought a food for my new dog and after one feeding I knew this wasn't going to work for her. So I went with a beef and oatmeal diet. I picked another food and am starting to slowly to add that to the beef/oatmeal mixture. Right now I know her system isn't ready for a full kibble diet, so slow and steady wins the race.
